Re: VDR prefers my CI DVB device for recordings and blocks it unnecessarily

The problem appeared with "Tagesschau" on ARD. Not every recording on ARD or ZDF has buffer problems, but when it is live and maybe even 16:9, it is very likely that it happens. And there is no chance to do an additional recording on the same transponder without problems. I always use very recent drivers from hg, never older than 3 weeks. I even patched it with the performance + refactoring patches http://www.vdr-portal.de/board/thread.php?threadid=51207 from Oliver ("UFO") which seems to make it a little bit better. >The driver I'm using is the Mercurial version 2006-02-05 (well, actually >that's not _that_ recent, anyway) and the firmware version F12623 as >of 2006-07-22. The size of my firmware file is 240044, and the md5sum >is 099329687c91131e616b4dcd8a118a25. My CPU is an AMD K6/II 450. F12623 ? where do you get it from? has it ever been released officially? I remember that Werner mentioned F12623 in vdrportal in June, but the last version which was posted there is F22623 from May

ProjectX and burn plugin
by Gavin Hamill 20 Aug '06

20 Aug '06

I'm posting this here for the lack of a better place. The ProjectX home page is a German-only forum, and as I don't speak German, that leaves me a little stuck. Basically, ProjectX 0.90.4 barfs as part of the burn plugin 0.1.0-pre20's work when I have a recording with 'Audio Description' soundtrack (a 64kbit mono mp2 track intended for blind people to describe what is happening on-screen). It's a bit annoying, since I don't even want this soundtrack included in the recording..

Making a cList object thread safe?
by Christian Wieninger 20 Aug '06

20 Aug '06

Hi, what is the best way to make a cList derived object thread safe? I have an object derived from cList and access it in the main thread and also in a background thread. The main thread access can modify the object (insert, edit, delete or even reload the complete list) while the background thread will only read the list. So e.g. a reload in the main thread could cause a crash in the background thread, if it just loops through the list. There are already some synchronisation methods in VDR (cMutex, cThreadLock,...). Is there any preferred method to solve my problem? Is there any plugin that already handled and solved this? Thanks, Christian

VDR with ATSC card -- need help
by mlists 17 Aug '06

17 Aug '06

Hi there, I have an Air2PC Skystar 2 card and a Twinhan 1020a. I've been using the Twinhan for several years now with VDR and am quite happy with how its working. I recently added the Air2PC card. Both are seen by the OS: 00:0b.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 00:0b.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 00:0c.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02) The twinhan is under /dev/dvb/adapter0 and the Air2PC is under /dev/dvb/adapter1. VDR verion 1.4.1-3 I confirmed in my sources.conf that I have an entry for C Cable. Would that be what to use for ATSC Cable (North America)? This is the single channel line I'm using to try and get this working: :@6 A-Channel:729:C0M256:C:0:21:24:0:1:6:0:0:0 Details are: Freq (Mhz) 729.0 QAM_256 C Video PID 21 Audio PID 24 CA 1 (for card number 1? -- does this start at 0? I've tried different numbers here) SID 6 (Same as channel I believe) Every attempt to change to this channel results in a "Channel not Available". Any suggestions?? Thanks in advance! Norm

[Fwd: QAM in vdr]

Clem sent me this email and asked me to share it with the list. He was able to get VDR working with ATSC. Please see below. Thx Norm -------- Forwarded Message -------- From: Herbert, Clem R. <<email addressed removed>> To: mlists(a)dressler.ca Subject: QAM in vdr Date: Thu, 17 Aug 2006 10:21:54 -0500 Hi Norm, I saw your post on the mailing list and I wanted to add to the info Klaus found (in a post from me). Sorry my old email is bad now, I opened it to avoid spam and didn’t use it enough so it was deleted ☹ I’ll try and find the best way to rejoin the list. BTW, I sent a copy of this to Klaus. It would be cool if you could repost this on the list in the meantime, for the other readers. Just please scramble my email address so that the spam bots don’t find me ;) Anyway, I managed to view ATSC OTA (8vsb with antenna) and QAM 256 (usa digital cable) here in Houston using that patch. I'm using the Dvico Fusion 5 Lite ATSC card. I don’t know anything about dvb programming (yet) so I can’t get guide info and such. Also, I made simple script to convert the azap output of dvb-apps/atscscan to convert the output to current vdr format (vdr output switch in atscscan complains that vdr won’t do ATSC). ************************************************** Cleaner ATSC patch diff -Naur vanilla/channels.c atsc/channels.c --- vanilla/channels.c 2006-03-16 21:48:57.285953250 -0600 +++ atsc/channels.c 2006-03-16 21:48:48.469402250 -0600 @@ -50,6 +50,7 @@ const tChannelParameterMap ModulationValues[] = { { 0, QPSK }, + { 8, VSB_8 }, { 16, QAM_16 }, { 32, QAM_32 }, { 64, QAM_64 }, diff -Naur vanilla/dvbdevice.c atsc/dvbdevice.c --- vanilla/dvbdevice.c 2006-03-16 21:48:57.289953500 -0600 +++ atsc/dvbdevice.c 2006-03-16 21:53:43.739855500 -0600 @@ -263,6 +263,19 @@ lockTimeout = DVBC_LOCK_TIMEOUT; } break; + case FE_ATSC: { // ATSC + + // Frequency and symbol rate: + + Frontend.frequency = FrequencyToHz(channel.Frequency()); + Frontend.inversion = fe_spectral_inversion_t(channel.Inversion()); + Frontend.u.vsb.modulation = fe_modulation_t(channel.Modulation()); + + tuneTimeout = DVBC_TUNE_TIMEOUT; + lockTimeout = DVBC_LOCK_TIMEOUT; + } + break; + case FE_OFDM: { // DVB-T // Frequency and OFDM paramaters: @@ -753,6 +766,7 @@ int type = Source & cSource::st_Mask; return type == cSource::stNone || type == cSource::stCable && frontendType == FE_QAM + || type == cSource::stCable && frontendType == FE_ATSC || type == cSource::stSat && frontendType == FE_QPSK || type == cSource::stTerr && frontendType == FE_OFDM; } ************************************************** End ATSC patch ***************************** Convert QAM azap to vdr channels.conf #!/bin/bash cat $1 | awk -F: '{ print $1":"$2":M256:C:0:"$4":0;"$5":0:0:"$6":0:0:"$6 }' ************************************************************** End ***************************** Convert ATSC azap to vdr channels.conf #!/bin/bash cat $1 | awk -F: '{ print $1":"$2":M8:C:0:"$4":0;"$5":0:0:"$6":0:0:"$6 }' ************************************************************** End

Parsing a pes packet
by Christian Gmeiner 16 Aug '06

16 Aug '06

Hi all. I want to parse a pes packet, which a vdr-device gets via its cDevice method (int cDevice::PlayVideo(const uchar* data, int length). I have looked at this page: http://dvd.sourceforge.net/dvdinfo/pes-hdr.html and i can parse pes, dts and other stuff. But i need some more informations like horizontal size and vertical size, which can be found in a sequence header (http://dvd.sourceforge.net/dvdinfo/mpeghdrs.html#seq). Can somebody help me with this task? I must say, that i dont know where to find the sequence header in the pes packet. Thanks, Christian
